Mustang seats bib should work. Don't know why it wouldn't but I certainly don't know everything. Give them a call.

Here is what I did...
I have a Danny Gray solo, and since Harley stopped making their stock fender cover, I searched Ebay for one. I found 3 in 3 months on Ebay, they ranged from 150 - 180 plus shipping, then I would have had to paint it. So instead I looked a mustang leather bibs. They in my opinion wouldnt look right, since they would put a black bib on my silver fender, keeping the 2-up look, not what I wanted.
So I found plastic trim panel push things at Advance Auto for 1.79 per pack. I got two packs and a can of Auto paint in silver metallic. Sprayed them that color, which matched perfectly and dropped them in the 4 holes. They were a touch to small, and moved around a bit, so I bought fuel injector o rings. They are a bit more heavy duty then reg. rubber o rings of that size. I slipped them on under the fender and they fit tight.
Of course you can see the raised trim rings, but it lets the lines of the fender still flow and they match well. All in all it was a $7 fix instead of a $30 mustang or $180 HD fix. and I think it looks better. Heres Pics.

 

Very clever Serge. Looks good.
